I'm Using The Fish Finder In Manual Mode, How Cani Set The Parameters For Optimal Operation; Can I Always Leave The Fish Finder In Full Auto/(Auto Gain And Auto Range) Mode?; What Are Extreme Situations In Which Auto Modes May Fail; What Should I Do If The Auto Modes Fail - Standard Horizon CP1000C Owner's Manual

7.4 I'M USING THE FISH FINDER IN MANUAL MODE, HOW CAN
I SET THE PARAMETERS FOR OPTIMAL OPERATION.
Setting operating parameters for optimal operation depends upon environment conditions,
user feeling and intended usage of the Fish Finder (e.g. fishing or cruising), anyway a good
starting point is to select a full auto preset such as CRUISE or FISH and then, after waiting
a while to allow the echogram displayed to stabilize around the auto calculated parameters,
switch to the MANUAL preset mode. At this point it will be possible to fine tune the operating
parameters by slightly changing the auto calculated parameters.
7.5 CAN I ALWAYS LEAVE THE FISH FINDER IN FULL AUTO/
(AUTO GAIN AND AUTO RANGE) MODE?
Yes, but note that the full auto mode suits the 90% of the cases, however in extreme
situations the auto modes mail fail and thus it is necessary to switch to the Manual mode.
7.6 WHAT ARE EXTREME SITUATIONS IN WHICH AUTO MODES
MAY FAIL?
When the bottom is very deep, at high boat speed, when the bottom is very shallow (< 5
feets), when the water is full of materials in suspension, with bad sea conditions.
7.7

WHAT SHOULD I DO IF THE AUTO MODES FAIL?

Failure of auto modes can happen for various reasons. Hereafter you can find a range of
possibilities.
7.8 AUTO-RANGE FAILS IN VERY SHALLOW WATERS DIS-
PLAYING A DIGITAL DEPTH READOUT DEEPER THAN THE
ACTUAL VALUE. WHAT SHOULD I DO?
This usually happens if the STC is set to LONG or MID and the bottom is shallow or SHORT
if the bottom is very shallow causing the auto-range to hook to the second or third echo from
the bottom (since in shallow waters the sound bounces more times back and forth the
surface to the bottom). Try decreasing the STC value to SHORT in shallow waters or to
switch it to VERY SHORT or OFF.
7.9 AUTO RANGE FAILS, AND THE DIGITAL DEPTH READOUT
DISPLAYS A VERY SHALLOW READING. WHAT SHOULD I
DO?
This usually happens if the STC is off or is set to a low value causing disturbs from surface
clutter to be stronger than bottom echoes. Try increasing the STC value. As general rule
STC has to be set as in shallow waters and LONG in depth waters.
